[PhilD]

The difference between Wesnoth (which I've been playing a lot these past months) and LoL (I've only played the demo) are in the design: Wesnoth is full of strategy and risk management, LoL has no randomness (that I can see) and simpler rules.

LoL is a rather abstract game, while Wesnoth is more of a simulation game (as much as a game with a fantasy theme can be a "simulation").

At the moment, Wesnoth wins in my book (and not just because it's free; running on my OS of choice is certainly a plus, though). I might still give LoL a try, though, for diversity. And a quick game is a nice thing, too; Wesnoth games can be pretty long.
